....would reduce their connectivity with the global TCP IP Internet, in response to rising security concerns. Such concerns have increased markedly in the past few years, after a number of well publicized events, such as a series of espionage attempts directed at U.S. government research laboratories [Stoll 1988], the Internet Worm of November 1988 [Spafford 1989] and other risks of being interconnected with interorganizational networks [National Research Council 1991] There are a number of different ways that sites might reduce their closeness of association with the Internet. The most extreme measure ....

....password. A guess at the user s password can be confirmed by calculating K c and using it to decrypt a recorded T tgs response. An intruder who has recorded many such login dialogs has good odds of finding several new passwords; empirically, users do not pick good passwords unless forced to. [Morr79, Gram84, Stol88] We propose the use of exponential key exchange [Diff76] to provide an additional layer of encryption. Without describing the algorithm in detail, it involves the two parties exchanging numbers that each can use to compute a secret key. An outsider, not knowing how the numbers were calculated, ....

....is more appropriate, though those of a classical bent may prefer Vandals , or even Goths or Visigoths . these log the request, and initiate counterintelligence strategies to learn something about the source of the request. We are certainly not the first ones to attempt to trick attackers[Sto88, Sto89, HM91]. But our motivation is somewhat different. We do not expect to prosecute, because (we hope) no damage will occur to our machines. This is not to say that the attackers do not try such things; see, for example, Che92] Nor, in general, do we care much about the identity of any particular ....
